SPECIFICATION forming part of Letters Patent No. 642,876, dated February 6, 1900.

Application filed March 21, 1 8 9 9.

To all whom it ntay concern.-

Be it known that I, ORLANDO H. PEOK, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Cameras; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to cameras, and is in the nature of an improvement on certain of the devices disclosed and claimed in the pending application filed by myself jointly with Charles L. Anderson, of date June 9, 1898, bearing Serial No. 682,980, and entitled Cameras. In the said prior application and in my present application a knife or cutter under spring tension to cutoff the film, in combination with a trip arranged to hold the cutter retracted and inoperative and to release the same at the proper times, is employed. In said prior application the cutting movement of the knife served to look the film-feedingmechanism,and henceit required with the mechanism therein illustrated a tripsetting device which required to be operated before the film feeding mechanism could again be actuated.

My present invention is particularly directed to an improvement whereby by a continuous movement of asingle driver or fingeroperated part the film-feeding mechanism will be given an interrupted or intermittent movement, and during the interval which the film-feeding mechanism remains idle the trip device will release the knife to permit its cutting movement and will restore the same to its retracted position.

To this end and to others hereinafter noted my invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

The invention in its preferred form is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a view in side elevation showing a camera to which my improved devices are applied. Fig. 2 is a vertical section taken transversely of Fig. 1,some parts being broken away. Fig. 3 is a view corresponding to Fig.

Serial No. 709,886. (No model-l 2, but 'with certain of the parts removed. Figs. at and 5 are views corresponding to Fig. 2, but with some parts removed and the parts being shown in difierent positions. Fig. 6 is a plan view of the parts shown in Figs. 3, 4., and 5; and Fig. 7 is a vertical section taken approximately on the irregular line 00" :0 of Fig. 2.

The numerals 1 and 2 indicate an ordinary camera box or case, the part 2 being the hinged end, which is secured to the body 1 by a hinge 3 and the ordinary catch or catches.

The numeral at indicates the frame on which the film-feeding mechanism, the cutter, and various other parts of the camera are mounted. This frame 4, together with the mechanism mounted thereon, is of course remov able from the boxor case l 2 in the ordinary manner. The film containing and guiding rollers are not shown, nor is it necessary for the purposes of this case.

The film (indicated at z) is fed between a pair of cooperatin g feed-rollers 5 and 6 of suitable construction, which are suitably mounted in the sides of the frame 4. and press the film in the ordinary manner. One of these feed-rollers-as shown, the roller 5-is provided on one projecting trunnion with aspurpinion 7.

Mounted on a stud or other suitable bearing 8 is a segmental spur-wheel 9, the teeth of which are removed or cut away throughout the smaller segment included between the points marked 9 and 9 This spur-wheel 9 is so positioned that its teeth will properly mesh or engage with the teeth of the pinion 7 when the said wheel is rotated, and hence, as is obvious, a continuous rotation of this wheel 9 will impart an interrupted or intermittent movement to the said pinion 7, and hence to the feed-rollers 5 and 6.

The segmental spurwheel 9 is provided with a supplemental and laterally-offset toothed section 10, the teeth of which work or pass to one side of the teeth of the pinion 7, and hence do not act thereupon. On a suitable stud l1,projected outward from a portion of one side of the frame 4, is a wide-faced spur-pinion 12, which is of such width and is so positioned that it always works in mesh with the teeth either of the segmental gear 0 or its supplemental section 10. Hence it will be seen that the gear 9, while segmental with respect to the pinion 7, is, when taken in connection with its supplemental section 10, a complete gear with respect to the driving-pinion 12. It is also evident that continuous motion of the said driving-gear 12 will impart a continuous motion to the gear 9 l0 and an interrupted or intermittent movement to the driven pinion 7, and hence to the film-feeding rollers 5 and 6.

Motion is preferably imparted to the driving-pinion 12 in the ordinary way by means of a finger-piece 13, the head of which is presented at the exterior of the box or case 1 and the stem of which is detachablysecurable by means of screw-threaded engagement or otherwise to the hub of the said pinion 12.

Suitably secured to and extending between the sides of the frame 4.- is the fixed member 14 of a pair of cooperating shear blades or cutters. The other member 15 of these cooperating shear-blades is pivoted, as shown at 16, for movement against the cutting edge of the said fixed blade 14 and with its free end terminated and working close to the segmental gear 9. A strong leat'spriug 17, one end of which is suitably secured to a fixed part of the frame l or other part rigidly secured thereto and the other end of which bears against the free end of ablade 15, puts the said blade 15 under tension to act and cut off the film. These two blades 14: and 15 are so positioned that the film z in passing from the film holder or roll to the feed-rollers 5 6 will be drawn directly between them.

The free end of the cutter 15 is for a very important reason bent laterally at approximately ninety degrees to the body of the cutter, as shown at 18, and the under surface or edge of this portion 18 is cut on a curved line for better engagement with the cam to be presently noted. That side of the free end of the cutter 15 which is opposite to the projection 18 works against the vertical guiding-surface of a projection 19 from one side of the frame 4:.

To the inner face of the segmental gear 9 is a segmental retaining-disk 20, which is cut abruptly away or inward toward the axis of the disk, as shown at 21, to form a recess into which the free end of the shear-blade 15 may fall in the cutting action. A cam-section 22, having a jog or shoulder, runs from the inner portion of the depression 21 out- Ward to the periphery of the disk 20. This cam-disk 2O 21 22 I designate as the knifetrip or tripping device. The laterallyturned free end 18 of the blade 15 works over and is engaged and supported by the periphery of the disk 20, which holds the said blade in its retracted or inoperative position against the tension of its spring 17. The disk 20 21 22 is so set with respect to the segmental gear 9, which carries it, that the blade 15 will be held retracted or inoperative during that interval of movement which imparts the feed movement to the feed-rollers 5 and 6 "and will release the blade or knife and permit the same to cut and then restore the said blade or knife to its retracted position during that interval of movement of the segmental gear 9 which leaves the said feed-rollers standing idle.

By reference to Fig. 4 it will be seen (the gear 9 being moved in the direction indicated by the arrows marked on the drawings) that the teeth of the segmental gear 9 have just been moved from engagement with the teeth of the driven pinion 7 and that a very slight additional movement of the said segmental gear will carry the abrupt shoulder or recess 21 of the disk 20 into line with the engaged free end of the shear-blade or cutter 15, thus first stopping the feed movements of the feedrollers and then quickly releasing the knife and permitting the same to cut. The cutting position of the blade or knife 15 is best illustrated in Figs. 2 and 3.

In Fig. 3 the cam-section 22 of the disk 20 is shown as just brought into engagement with the correspondingly-formed portion of the laterally-bent extremity 18 of the blade 15. Under continued movement of the gear 9 and disk 20 in the direction indicated the camsection 22, acting on the portion 18, will cam the blade or knife 15 back into its normal position, as indicated in Fig. 5. Again, noting Fig. 5, it will be seen that while the said blade or knife 15 has been restored to its normal position the teeth of the segmental gear 9 have just reentered into engagement or mesh with the teeth of the driven pinion 7, so that further movement of the said segmental gear will impart the next feed movement to the filmfeeding rollers. Of course it would be possible to cam the blade or knife 15 back to itsnormal position even if it did not have the later ally-offset cam-engaged end; but nevertheless this offset portion is important, as it relieves the blade to a very considerable extent from side thrusts under the camming action thereon and permits it to be restored by a cam extending through a much shorter segment or arc.

XVith the construction so far described the operation will be as follows: The parts will probably be left normally standing as indicated in Figs. 2 and 3, although they might be left standing in the position indicated in Fig. 5. After an exposure has been made the manipulator of the camera turns the driving-pinion 12 by means of the finger-piece 13 until the gear 9 has been moved from the position indicated in Fig. 3 or in Fig. 5 into the position to release the knife and cut off the film-section. When the knife is thus released, the gears, being loose, may be much more easily turned for a short distance, and this will serve to indicate to the operator when the film has been cut. Furthermore, a little additional movement of the gears will bring the cam 22 into engagement with the cam end 18 of the knife, and thus additional work will be put upon the gears, and this camming action will tend to IIO produce a reverse movement of the gears, both of which actions will be distinctly felt by the operator and may by him be noted as another means for determining the proper place to stop the movements of the driving gear or pinion and parts moved thereby. This construction has the further advantage that it is not necessary to stop the movements of the segmental gear with any particular accuracy or at any exact point, inasmuch as film-sections of the exact and predetermined length will be out if the said segmental gear and parts carried thereby are stopped at any point between the approximate limits indicated in the one instance by Figs. 2 and 3 and in the other i11- stance by Fig. 5. v

In imparting the driving motion to the drivin g-gear 12 the operator naturally gives halfturns to the finger-piece 13 and at each movementtakes a new hold on the said finger-piece. One half-turn of the gear 12 is not sufficient to move the cam 22 from the position indicated in Fig. 3 into the position indicated in Fig. 4, and hence there would be a tendency for the partially-raised knife to throw the said cam and segmental gear backward while the operator is getting a new hold on the said finger-piece. Vith my construction illustrated the jog or shoulder 22 in the cam 22 will serve to hold the free end of the knife partially raised while the operator is getting a new hold on the said finger-piece. It also results with this construction that a positive stop or look for the film-feeding mechanism is not required to give accuracy in the length of the film-sections; and since the lock is dispensed with a special device for releasing the lock is also dispensed with, and it is made possible, since the feed mechanism is not locked, to utilize a certain portion of the movement of the motion-transmitting mechanism to restore the knife or cutter to its normal position while the film-feeding rollers remain idle.

It will sometimes happenas, for example, when a panorama-picture is taken-that a film of the length of several ordinary filmsections should be left intact or connected. I provide for this operation bya simple device, the preferred form of which is illustrated in the drawings. This device I term the knife intercepter or stop, and in its preferred form it consists of a short shaft 23, passed through and suitably mounted in the hinged end 2 of the box or case and provided at its inner end with a laterally-projected finger 24. At'its outer end the shaft 23 is provided with an arm 25, which serves to move the shaft 23 and to indicate the position of its stop-finger 24E. TVhen this device is not required for use, it will stand as indicated by Figs. 1 and 2, and when moved in its operative position, (indicated in Fig. 7,) the stop-finger 24 will be carried under the transversely-turned portion 18 of the knife or shear blade 15, in which position it will act as a stop to prevent the said knife or cutter from being thrown into its cutting position when released by the disk 20.

It is, however, desirable to so locate the stopfinger 24 that the knife when released will be given a slight downward movement before it is caught by the said stop-finger. This being done, the action of the cam 22 on the free end of the knife will be required to force the said knife back into normal position above the periphery of the retaining-disk 20, and this camming action will be very apparent to the operator, who, noting the same, is thus enabled to count the number of film-sections, or rather lengths of film-sections, which have been fed or unreeled. For example, if a film of the length of seven ordinary film-sections is desired the operator would turn the stop finger 24 below the free end of the knife and would feed the film by turning the finger-piece 13 until six sections had been fed past the knife, and would then turn the stop-finger 24 into its inoperative position and continue the feeding movement until another length of film had been fed or moved past the knife, at which time the knife would be actuated or released and cut off the long film-section.

It will of course be understood .that myinvention above specifically described is capable of many modifications in the details of its construction and arrangements of its parts.
